Application of system dynamics for assessment of sustainable performance of construction projects

INTRODUCTION Sustainable development is commonly definedas meeting the needs of the present without compro-mising the ability of future generations to meet theirown needs (WCED, 1987). All industries, includingthe construction industry should contribute to themission. Compared to other industries, constructionactivities are generally considered to have more im-pact on the environment, which provides the basicconditions for the sustainability and development oflife on the Earth.

Cognitive correlates of visual speech understanding in hearing-impaired individuals

This study examined the extent to which different measures of speechreading performance correlated with particular cognitive abilities in a population of hearing-impaired people. Although the three speechreading tasks (isolated word identification, sentence comprehension, and text tracking) were highly intercorrelated, they tapped different cognitive skills. In this population, younger participants were better speechreaders, and, when age was taken into account, speech tracking correlated primarily with (written) lexical decision speed. In contrast, speechreading for sentence comprehension correlated most strongly with performance on a phonological processing task (written pseudohomophone detection) but also on a span measure that may have utilized visual, nonverbal memory for letters. We discuss the implications of this pattern.

Evidence for the role of higher order reasoning processes in cue competition and other learning phenomena

When people judge the contingency between a target cue and an outcome, they also take into account the contingency between the outcome and other cues with which the target cue co-occurred. Several authors have argued that such cue competition effects are due to higher order reasoning processes. We review the evidence that supports this hypothesis and discuss whether higher order reasoning might also play a role in other learning phenomena.     

Special needs of the deaf dying patient

Hospice and hospital personnel who give care to dying patients should be prepared for situations in which a client or family member is hearing impaired. What are the specific concerns of a hearing impaired client? How are needs for meaningful conversation and expression of feelings compromised by the care giver's awkwardness? This article provides practical suggestions for meeting needs of hearing impaired clients with serious illnesses.

具帽真菌直观教具的制作

高級菌类子实体的保存,通常是浸制在專門的溶液里,这样,真菌在一定程度上变得粘滑,并且失去了固有的自然形态。在我多年的試驗中証明,多孔菌科和松蕈科真菌的子实体,在用融化的羊脂()并加少量(5—10%)萘或莰处理后,能保存得很好。子实体的处理及其制作的进行,是按以下一定的順序进行: 1)鉋一直徑为3—5毫米,長度取决于真菌的小棒;棒的一端削尖; 2)將小棒插入菌柄末端已經切断的子实体內,小棒要插在菌帽厚层的中央(图1); 3)握住小棒露出之一     

Initiations of social interactions by young hearing impaired preschoolers

This study examined strategies for initiating social interactions with peers, among 4 children with hearing impairment, aged 33 to 36 months, attending a special early education center or a regular kindergarten. The study investigated initiation type (related to partner's hearing status) and rates of initiation success/failure vis-a-vis hearing and deaf partners. Results revealed (a) more initiations in the regular program than in the special program; (b) in the special program, much more successful initiations toward children with hearing impairment than toward hearing children; (c) vocalization as the most frequent strategy used with both hearing and hearing-impaired partners; and (d) referential decisions about their initiations even among young children with hearing impairment (made by changing frequencies of various strategies according to partner's hearing status). The discussion addressed implications regarding integration of children with hearing impairment into regular educational settings.     

报废的承诺

在中国,老夫老妻之间喜欢用“老伴”来称呼,老伴老伴,老了来相伴,想起了一首很经典的歌曲里的那句歌词：“我能想到最浪漫的事,就是和你一起慢慢变老。”天长地久的爱情总是让人羡幕和渴求的,尽管恋人抑或夫妻间偶尔会有摩擦,但心里最想的还是让自己的另一半幸福,就像文中的那位太太,报废了一个承诺又怎样?只要老伴你幸福。售货员的“给予”也是感动人心的,显示出了人性中的闪光点。成全是一种美德,成全你爱的人获得幸福,成全和你一样呼吸着的人获得幸福。
